Is the Markdown editor free?

Yes. The editor is completely free with no sign-up, no limits and no watermarks. Everything runs in your browser.

Where is my text stored?

Your document is saved locally on this device using your browser's storage. It is never uploaded to a server, so your writing stays private and is restored the next time you open the tool.

Can I export to HTML?

Yes. Use Export .html to download a self-contained HTML file with your Markdown rendered as headings, lists, links and code — ready to open or publish. You can also export the raw .md file.

Can I open an existing Markdown file?

Yes. Click Open .md to load a .md, .markdown or .txt file from your device straight into the editor, then keep writing and re-export when you're done.

Does it work offline?

Once the page has loaded, the editor runs entirely in your browser, so writing, previewing and exporting all keep working without a connection.

What it does

The Carbide Markdown editor is a free, in-browser writing space for notes, READMEs, documentation and any text you want formatted with Markdown. Type in the Edit tab and flip to Preview to see it rendered, or use the split view on a wide screen to watch both at once. A formatting toolbar inserts headings, bold, italic, links, lists, code blocks and more, so you never have to remember the syntax. Your work autosaves to this device as you type and reloads when you come back — nothing is uploaded, so it stays private and works offline-friendly once the page has loaded. Open an existing .md file straight into the editor, and when you're done, export the current document as a clean Markdown file or as rendered, self-contained HTML you can publish anywhere. You can also copy the raw Markdown or share it with one tap. A live word, character and line count keeps you oriented while you write.
